Adif Mcp

If you're working with amateur radio logs, this gives Claude direct access to ADIF 3.1.7 validation and parsing. You get eight tools: validate records against spec, parse large log files with pagination, search the full enumeration database for bands and modes, and run geospatial calculations on Maidenhead locators for distance and beam heading. It's the foundation layer in a larger qso-graph ecosystem that includes separate MCP servers for eQSL, LoTW, QRZ, POTA, SOTA, and propagation data. Useful if you need to validate imported logs, cross-reference field definitions during development, or calculate QSO geometry without leaving your editor.
